In1909,Johannsen coined the word "gene", shortened from the pangene of de Vries and ultimately derived from Darwin's word pangenesis,to denote the unit of heredity.

弗里斯创造的"泛生子"一词缩短而成的，而"泛生子"一词则衍生于达尔文提出的"泛生论"。

Mendel's concept was given a name by Hugo de Vries in 1889, who, at that time probably unaware of Mendel's work, in his book Intracellular Pangenesis coined the term "pangen" for "the smallest particle one hereditary characteristic".

An expert on Netherlands flora, De Vries showed that turgor pressure of the fluid in plant cells was partially responsible for growth and coined the term ' plasmolysis ' for the effect on cells of water loss during wilting.

It is shown that two-component Wadati-Konno-Ichikawa equation, i.e. a generalization of the wellknown WKI equation is obtained from the motion of space curves in Euclidean geometry, and it is exactly a system for the graph of the curves when the curve motion is governed by the two-component modified Korteweg-de Vries flow. At the same time, a n-component generalization to the WKI equation is obtained. Also, starting from the motion of curves, mKdV and its symmetry recursion operator is exhibited explicitly; two- and n-component mKdV systems are obtained. It is shown that WKI systems are gauge equivalent to mKdV systems. The two-component WKI equation admits an infinity number of conservation laws and a recursion formula for the conserved densities is given by considering an eigenvalue problem together with introducing an appropriate transformation.

In his book Why Pray? Rev. John De Vries asks,"Does it pay to pray?" Sometimes praying seems like a waste of time.

The theories proposed by Wilson (1994) were adopted to describe the fundamental behaviors of temperature and variation of suction of soil. The Darcy's law and Pick's law described the flows and evaporation of water respectively. Some proposed assumptions including the characteristic curve of volumetric water content and hydraulic conductivity were only related to the suction of unsaturated soil. The coefficient of latent heat for water was a linear function of temperature; and the heat conductivity was calculated according to the equation proposed by De Vries.

对于土体的温度和吸力变化特征，采用Wilson提出的理论加以描述，在此理论中，分别利用Darcy和Fick定律描述水和蒸汽的流动规律，土水特征曲线和水力传导系数假定仅仅相关于非饱和土吸力，水的潜热系数是温度的线性函数，温度传导系数采用De Vries建议方程加以计算。
